When the engine is running, a small part of the oil is pumped from the oil pump and enters the filter through the oil port. Then it enters the rotor body through the oil hole and ejects from the two nozzles, so the ejection reaction force pushes the rotating hand to rotate. Under the action of the rotating centrifugal force, they are thrown to the rotor wall, and Attach the cover to the wall.

When the oil pressure is lower than 9s kPa, the oil inlet pressure limiting valve is closed and the fine filter does not work. When the oil pressure rises to 294 kPa, the speed of the rotor can reach 5000r/min or more, and the specific gravity of impurities in the lubricating oil in the rotor cavity is larger than that of the lubricating oil.When the oil pressure exceeds 98 kPa, the pressure limiting valve is gradually opened, and the oil is sprayed from the oil outlet through the center hole of the rotor shaft.

It is connected to the oil inlet of the oil pump. Float type oil filter, in order to make the oil pump work well, the large particles in the lubricating oil must be removed before entering the oil pump. A compression nut fastens the rotor cover and the rotor body together. In order to achieve a satisfactory filtering effect without increasing the resistance of Casting Automotive Mould Manufacturers the oil passage, the coarse filter is generally connected in series with the main oil passage, and the fine filter is connected in parallel with the main oil passage. The clean lubricating oil at the center enters the two nozzles from the center and continuously sprays outward, and the sprayed lubricating oil flows back to the lower crankcase.

It is mainly composed of upper cover, shell, paper filter element and bypass valve. parts-its function is to filter out smaller impurities in the lubricating oil. When the oil pump is working, the oil is sucked in from the slit between the cover and the float, filtered through the filter screen to remove coarse impurities, and then enters the oil pump through the oil pipe welded to the float.

Aluminum casting is due to the large latent heat of condensation to a certain extent. Aluminum casting has outstanding casting functions. Production costs should be reduced from the perspective of planning and technology, such as using one-mold multi-part skills and automation skills to increase production rates, extend mold service life, and use integrated planning to reduce the number of parts.

Pure aluminum and aluminum alloys have outstanding thermal conductivity, and are used in heat exchange equipment used in chemical production, as well as parts that require outstanding thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines., which make it widely loved by users, especially since the lightweight of cars, cast aluminum alloy castings have been used in the car industry Has been widely used.

Because of its low melting point, casting methods such as metal molds and pressure casting are widely used, which can improve the inner quality of its castings, its dimensional accuracy, appearance smoothness, and production power. The requirements for aluminum castings for cars are developed in the direction of thin wall, messy shape, high strength and high quality.. Under the same weight, the condensation process of molten aluminum is much longer than that of cast steel and cast iron at all times.

There are still many problems to be dealt with for aluminum casting to form its large-scale production and satisfy the requirements of lightweight cars.Aluminum casting has some incomparable advantages when used in other castings, such as its beauty, light weight, corrosion resistance, etc. The liquidity is excellent, which is beneficial to casting thin-walled and disorderly structured castings. Aluminum casting has outstanding appearance gloss and excellent corrosion resistance in the atmosphere Four Cylinder Head Manufacturers and water, so it has a wide range of uses in the production of civil utensils.

The density of cast aluminum alloy is lower than that of cast iron and cast steel, but the specific strength is higher. Pure aluminum has outstanding corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings also have certain uses in the chemical industry. Therefore, the selection of aluminum alloy castings under the same load conditions can reduce the weight of the structure. Therefore, in the aviation industry, power machinery and transportation machinery, Aluminum alloy castings are widely used. To get used to this requirement, the casting process should be further optimized and new alloy materials should be developed
